I-Pyridinium p-Toluenesulfonate (i-CAS: 24057-28-1) isetyenziswe njengendawo ephakathi kwi-organic synthesis.Isetyenziswa njengemichiza eqhelekileyo kwimizi-mveliso.Isetyenziswa njengomthombo onyibilikayo wePyridium ion.Iphakathi kweTacrolimus kunye ne-Orlistat Immunosuppressant, i-anti-obesity / pancreatic lipase inhibitor.Kwi-organic synthesis, i-PPTS isetyenziswe njenge-catalyst ene-acidic ebuthakathaka, inika umthombo we-organic soluble we-pyridinium (C5H5NH +) ion.Kwakhona i-catalyst esetyenziswa ngokuqhelekileyo ukulungiselela i-acetals kunye ne-ketals esuka kwi-aldehydes kunye ne-ketones.Njenge-co-catalyst kunye ne-L-proline kuphuculwe zombini isivuno kunye ne-enantioselectivity ye-asymmetric aldol condensation phakathi kwe-dioxanones kunye ne-aldehydes.
